TELEPHONE-REMINDER.

Application filed August 12, 1919.

adapted to practical use, which is also simple in construction and operation, and inexpensive in cost of manufacture.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a perspective view of my device, showing its construction and operation.

Fig. 2 is a view of my device attached to an ordinary telephone set, ready for use.

Referring now in detail to the drawings, 1 represents the frame or body of my device, which may be conveniently made of paste-board, heavy paper, leather, tin, or any suitable material. The surface of my device is divided as shown by parallel horizontal lines, and by parallel vertical slots 8, 9, 10, 11, 12, and 13. The frame 1 is provided with ears or the like 15 folded about the line 14 having perforations or holes therein for the purpose of attaching the device to the telephone set. At the left in the spaces between said horizontal lines are written the names of the exchanges in the city or town where the device is being used. In the spaces between said horizontal lines and between said vertical slots are written the numerals 1 to 9, and zero at the bottom, as shown. The columns of said last named numerals are indicated by reference characters 3, 4, 5, 6, and 7 the last column, however, being provided with the letters commonly used in calling party line phones. Arrows 16 are slidably mounted in said vertical slots.

The particular utility of my device is noticeable when it is necessary to jot down Specification of Letters Patent.

Patented Apr. 20, 1920.

Serial No. 317,006,

a number while telephoning and when a pencil or other marking means is not readily available. The difficulty thus encountered has been experienced time and again by most telephone users. It is apparent that, by permanently attaching my device to the telephone as shown in Fig. 2, a number may in a few seconds be recorded, as received over the phone, by simply moving the various arrows to the proper positions to indicate the desired exchange, number, .and party letter, 1f any.

The simple method of attaching my device to a telephone set is illustrated in Fig. 2, which shows the frame 1 secured to the back of the wall set 17 by means of tacks, nails, or screws 18. My device may likewise be readily attached to a desk set or any other style of telephone set by stringing a wire or cord through the holes in the ears 15 and enveloping the stem of the set, or other member, therewith and securing the same thereto.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent is as follows:

A device of the class described comprising a frame having a plurality of equidistant horizontal lines drawn across the surface thereof, a plurality of equidistant vertical slots in said frame, indicating arrows slidable in said slots, said slots being so pro portioned as to leave a relatively wide column and a plurality of relatively narrower columns, said wide column being located to one side of said narrow columns, the names of telephone exchanges being contained in said wide vertical column, numerals one to ten, inclusive, being contained in each of said narrow vertical columns in serial order from top to bottom, and an extension hingedly attached to the left-hand side of said frame and provided with ears, one at the top and the other at the bottom thereof, each of said ears having a perforation therein.

Signed at Detroit in the county of Wayne and State of Michigan this 1st day of August, A. D. 1919.
